Civil Contractor Drives Model-to-Field Integration
Fiore & Sons, the civil contractor for the Trimble Rockies Campus Westminster Building Phase 2 project, have combined several Trimble technologies to deliver a comprehensive technology-driven, highly accurate and fast design-to-field earthworks solution.
The Westminster Building Phase 2 earthworks and utility work requires the movement of approximately 37,000 cubic yards of dirt and approximately 5,000 cubic yards of borrow material. The building pad must be over-excavated 8-feet below bottom of slab and 10 feet outside.
The crews will also carry out the utilities work for storm, sanitary and water, build the retaining walls, footers and grade beams, grade the parking area for the curb laying operations and trim the parking areas and roadways in preparation for the paving operations.
Fiore and Sons design team used Business Center-HCE heavy construction design solution for data preparation and takeoff as well as the development and management of all 3D site models. Fiore imported 3D CAD design linework files from Martin/Martin civil engineers to Business Center-HCE.
The finish grade model shows all of the finished surfaces on the project including roads, parking, walkways, islands, loading bays and all landscaping and retaining walls.
Fiore and Sons use on Trimble Connected Community (TCC) project collaboration portal to track project progress and earthwork activity in real-time and online with greater efficiency and ensure all information is readily available to all team members on and off site and to feed data to VisionLink, Trimble’s site productivity and fleet management solution.
The 3D models were then loaded onto the wheel loader and scraper quipped with a Trimble GCS900 grade control system.
Since earthwork began at the site, Fiore has relied on VisionLink to integrate site productivity, material quantities, materials movement and managing daily load counts
Justin Russell, surveyor with Fiore & Sons, says, “We’ve been using VisionLink for four years now. We’re not undercutting or overfilling—and we know exact quantities, within inches, on a daily basis for billing. It’s helped immensely to manage real-time quantities.”
